Abstract
In an up-down tuner in which a printed wiring board and a metal chassis penetrating a slit formed in the printed wiring board are bonded by solder with each other, a grounding plate provided with soldering portions having an approximately L-shaped profile is incorporated in an engaged state with the metal chassis. The printed wiring board and the metal chassis are soldered to each other via the soldering portions.
Claims21
An up-down tuner in which a printed wiring board is soldered to a metal chassis that penetrates a slit formed in the printed wiring board, comprising:
- a grounding plate, engaged with the metal chassis, including at least one soldering portion having an approximately L-shaped profile, via which the printed wiring board and the metal chassis are soldered together, wherein the at least one soldering portion includes a through-hole.
An up-down tuner in which a printed wiring board is soldered to a metal chassis that penetrates a slit formed in the printed wiring board, comprising:
- a grounding plate, engaged with the metal chassis, including at least one soldering portion having an approximately L-shaped profile, via which the printed wiring board and the metal chassis are soldered together, wherein the grounding plate includes a first portion extending along one side surface of the metal chassis, a second portion extending along the other side surface of the metal chassis, and a connection portion for connecting the first and second portions together, the connection portion being engaged with a corresponding portion of the metal chassis, and wherein the at least one soldering portion is formed at a lower end of at least one of the first and second portions.
An up-down tuner in which a printed wiring board is soldered to a metal chassis that penetrates a slit formed in the printed wiring board, comprising:
- a grounding plate, engaged with the metal chassis, including at least one soldering portion having an approximately L-shaped profile, via which the printed wiring board and the metal chassis are soldered together, wherein the metal chassis includes a cutout portion for retaining the printed wiring board, and the grounding plate includes a shield portion in positional correspondence to at least the cutout portion.
An up-down tuner in which a printed wiring board is soldered to a metal chassis that penetrates a slit formed in the printed wiring board, comprising:
- a grounding plate, engaged with the metal chassis, including at least one soldering portion having an approximately L-shaped profile, via which the printed wiring board and the metal chassis are soldered together, wherein the soldering portion of the grounding plate includes two spaced nails.
A soldering plate for soldering a metal chassis to another element, comprising:
- a first portion extending along a first surface of the metal chassis;
- a second portion extending along a second surface of the metal chassis;
- and
- a connection portion for engagement with a corresponding portion of the metal chassis and for connecting the first and second portions together;
- and
- at least one approximately L-shaped soldering portion formed on at least one of the first and second portions.
